[R] HOW TO REMOVE MTEXT FROM PLOT, plotting changing populations with titles in loop

[prinzOfNorway]

is there a way to hide/undraw mtext (or lines etc.) in a loop like

plot(runif(10))
iterCol <- rainbowPalette(10)

for(i in 1:10){

mtext(paste("this is iteration ", i, sep=""))
points(runif(10),col=iterCol[i])
Sys.sleep(1)

## UNDRAW/HIDE the text so that it does not mess up the plot in the next
iteration

}
